An interesting experiment about web-browsing habits I just invented, which I'll call "Alphabrowsing":
1. Go to your web browser address bar, and type one letter.
2. Write down the first auto-complete suggestion the browser makes.
3. Do this for every letter.
4. Report on the results, especially commenting on which ones surprised you.
I, Q, and R are the most surprising ones to me. "I" was a place I stayed at a few months ago, but I guess there haven't been many other websites since then that start with I. "Q" I just looked at 30 minutes ago, for the first time. And "R" I check maybe every two months when the joking-around in the household gets blue -- but really, are there no other websites I visit more frequently that start with "R"?
I also made a simple pie chart categorizing the results. Note that I categorized things under the reason I go to the site, not necessarily the site's purpose. E.g., rule34.paheal.net is under "Humor" because I mostly use it for shock humor, and thesaurus.com is under "Puzzles" because I usually go there for some sort of puzzle research.
Here are the raw results:
